I use Number of the Day PowerPoint along with Number of the Day worksheets daily to assist students with number sense skills. The Power Point changes as the number becomes larger to include more skills needed. Tools used to address skills are ten frames, number lines, part part whole, greater and less than, coins, tally marks, hundreds charts, place value, number words, and much more.
Open the PowerPoint to start slide show. Select side and click on "begin with current slide". Then just click your mouse.
